Medical Kegel balls for men
* NOTE: We use the term “Kegel balls”. This also includes “Ben Wa balls, Geisha balls, vaginal balls, pelvic-floor training balls”, etc.: a solid ball that rotates inside a hollow ball and, with movement, produces vibrations for stimulation.
Stimulate pelvic floor, potency and prostate with Kegel balls* for men
With Viball® Kegel balls* for men you strengthen the healthy function of your pelvic floor, your male vitality and your continence. They support a firm erection during intercourse, work effectively against incontinence and haemorrhoids, and demonstrably reduce the risk of prostate cancer.
With Viball® Kegel balls* you can - without medication, special diet or exercises - stimulate prostate and potency and build a strong pelvic floor. Simply wear them in everyday life: you insert the ball into the anus with gentle pressure of a finger, where it continuously creates prostate stimulation. Viball® Kegel balls* are real therapy balls - certified medical devices with proven effect - with the pleasant “side effect” of intense erotic stimulation, because the prostate is your male G-spot.
One Viball® Kegel ball* massages the pelvic floor, prostate and root of the penis through vibration - with every movement in daily life or during sport. In this way it supports the healthy function of prostate, pelvic floor and potency and is also highly effective against haemorrhoids.

What makes Viball® unique
Every detail of a Viball® is uncompromisingly geared towards quality. Our claim at Theros: to build the best Kegel balls* in the world. The facts speak for themselves:
- Only Viball® Kegel balls are made of high-grade implant steel rather than silicone. “Pure ball”, no frills, with a polished surface. This makes them - uniquely among Kegel balls—particularly suitable for prostate stimulation in men: easy to insert, ultra-hygienic, free from harmful substances and maximally efficient.
- Thanks to precisely calculated components, every Viball® delivers the most intense stimulation of all Kegel balls* -physically, you can’t get more! Ideal for activating prostate function, training potency and pelvic-floor muscles, and against incontinence or difficulty urinating.
- Immediate stronger erection during intercourse through tapping impulses that intensely stimulate the prostate with coital movements - for desire, love and fulfilling sex.
- Six sizes for beginners and advanced users: from small (36 mm) to very large and heavy, as a single ball or a pair.
- Usable anytime, anywhere, because Viball® sits completely inside the body—unseen by others.
- Also usable vaginally during intercourse for women - for deeper contact and stronger orgasm.
- Extremely sustainable and 100% recyclable: permanently hygienic, no silicone waste, no environmental burden.
- Certified medical device with proven efficacy and CE-certified application safety.
Use cases for Viball® Kegel balls*
- Pelvic-floor problems (often linked with back pain) - plus pelvic-floor training with balls
- Activation of prostate function, in prostate issues such as prostatitis or prostate enlargement
- Erectile weakness (preventive)
- Immediate enhancement of erection during sex through prostate stimulation (tapping impulses)
- Incontinence
- Haemorrhoids (Piles)
Six sizes from 36 - 60 mm for every man
Viball® Kegel balls* come to fit every man - whatever size you need: from small to very large and heavy, from first rectal experiences to “advanced”. Tips on the optimal size can be found under “Frequently asked questions”. If 36 mm feels too much at the beginning, you can gently and quickly open up with our FMS dilators—also to accommodate larger models that stimulate your prostate even more intensely.
World-leading efficiency
Conventional Kegel balls* designed for women often create too little impulse strength for the prostate. In Viball® Kegel balls*, the ratios of inner to outer ball are precisely calculated for each size. The vibrating inner balls are made of stainless steel, the outer balls even of hypoallergenic implant steel AISI 316L. Density, resonance and transmission into the body are many times more intense than with silicone.
Immediate erection boost through prostate stimulation
During movements in intercourse, Viball® Kegel balls in men create a tapping massage on the root of the penis and the prostate that strengthens the erection - completely naturally, without medication. As ball size increases, the effect rises exponentially - even more intensely when used simultaneously by a partner.
Extra stimulation through mobility in the area of use
A Viball® moves in interplay with your muscles, because the spherical shape and mirror-polished surface prevent fixation or tissue adhesion - unlike segmented shapes or models with strings that can get stuck. This additional movement stimulates the root of the penis, sphincters and prostate—unique to Viball®. Anatomically, the ball cannot travel beyond the rectum deeper into the body. Even if it is moved further by external manipulation, natural bowel activity will remove it again - a ball, unlike elongated sex toys, cannot become wedged.
No retrieval string? Sure - and absolutely safe!
Protruding “retrieval strings” are unhygienic - especially in rectal use. Removing a Viball® without tools is practical for every man and explained in the instructions for use. Viball® Kegel balls cannot “disappear” in the body - proven application safety as a medical device guarantees this.
A special medical application sleeve for pulling out is only useful in rare anomalies (e.g. spasms, scarring, anal cramp). These sleeves are available at a low price in our shop.
For safety, every Viball® comes with a medical application sleeve for the “first time”. This way you can stimulate your prostate without risk and test removal.
Haemorrhoids? Viball® helps - and prevents
Viball® Kegel balls can reduce (reposition) existing haemorrhoids and prevent them from prolapsing again. For inflamed haemorrhoids, cooled application (refrigerator) is suitable as cold therapy - see instructions for use. For acute treatment of inflamed haemorrhoids we additionally recommend our FMS dilators for more intensive cooling and targeted repositioning. Intensive prostate massage -with or without orgasm - also becomes much easier with dilators than with a finger.
“Milking the prostate” for health and wellbeing
The so-called “milking” of the prostate (prostate orgasm) works via prostate massage—with gentle pressure using a finger or with a tool such as the Theros® ProstaSphere. This stimulation of the male G-spot helps with prostatitis or acute inflammation, promotes secretion flow and helps prevent prostate cancer. Unfortunately, only few therapists offer this treatment. With prolonged, intensive movement, large Viball® Kegel balls can also stimulate the prostate strongly enough to trigger a prostate orgasm.
No feeling during intercourse anymore? Viball® helps
A common topic: a size mismatch between penis and vagina - the result is too little contact between the genitals, weaker erection for the man, absent orgasm for the woman. Vaginal use of a Viball® in a suitable size naturally creates deeper contact: the mirror-polished surface prevents skin irritation; the ball doesn’t feel like a foreign body but intensifies contact - also through gentle vibration. In addition, it improves the ability to reach vaginal orgasm by stimulating the cervix and G-spot and gives both partners a new, intense experience.
Premature ejaculation
With larger balls, the tapping prostate massage during intercourse is perceived more consciously. Combined with focus techniques, this can counteract a premature orgasm or ejaculation (ejaculatio praecox).
Viball® is a certified medical device
Viball® is a certified medical device and meets all legal requirements for application safety and proven efficacy for prostate stimulation. Implant steel AISI 316L meets clinical standards for biocompatibility and hygiene - even with years of use.
Implant steel instead of silicone – reasons why:
- Optimal oscillation properties and best possible transmission of vibration into the body
- Higher weight = stronger vibration intensity for prostate stimulation
- Highest biocompatibility, no binders as with silicone
- Polished surface: mobile in the body, gentle in contact with tissue and genitals
- 100% odour- and stain-resistant compared with silicone - permanently hygienic
- Maximum longevity and sustainability
Invisible to others - wherever and whenever you want
Viball® Kegel balls* remain invisible in any situation, because—like an implant—they are completely inside your body, even during sex. If you like, it remains your sensual secret and you surprise your partner with the effect.
Viball® - good for health, for couples and for love.
